AMILE D. BISHOFF, OF BUTLER, PENNSYLVANIA.

RAIL-JOINT.

Application filed June 4, 1920. Serial No. 386,441.

I 0 all whom it may concern Be it known that I, AMILE D. BIsHorr, a citizen of the United States, residing at Butler, in the county of Butler and State of Pennsylvania, have invented new and useful Improvements in Rail-Joints, which the following is a specification.

This invention relates to securing means, and more particularly to a joint for securing the adjacent ends of rail sections.

One of the main objects of the invention is to provide a rail joint of simple construction and operation which may be produced and applied at low cost, and which will effectively brace the rail head. Another object is to provide locking members which'operate in planes at right angles to each other so as to eliminate loosening of the joint. A further object is to so relate the locking members that one of them acts as a stop to positively prevent movement of the other member into inoperative position. Further objects will appear from the detailed de scription.

In the drawings Figure l is a side view of ajoint constructed in accordance with my invention.

Fig. 2 is a section taken substantially on line 2-2 of Fig. 1.

Fig. 3 is a section taken substantially on line 33 of Fig. 1.

Fig. at is a side view of one of the securing bolts.

Fig. 5 is an end view of the same.

Two plates 1 and 2 are placed at opposite sides of the base andweb portions of rail sections 3, plate 1 fitting snugly about the base flange of each rail section and extend ing beneath the same.

late 2 is provided at its upper end with an inwardly extending shoulder 4 which fits snugly between the shoulder of head 5 of rail section 3 and the upper edge of an inner locking plate 6 which rests upon the upper face of the base flange of the rail section and fits snugly against the web of the rail. Plate 1 is extended to fit snugly under theother shoulder of the rail head as illustrated in Fig. 3.

Plate 1 and the web 7 of the rail section are provided with alined openings which receive the squared body 8 of securing bolts 8. Each bolt is provided with a reduced threaded element 9 upon which is screwed a nut 10, this nut being held against reverse rotation by a locking washer 11 of known type, or in any other preferred manner. Body 8 of the bolt is provided in one lateral face, and adjacent to the end thereof remote from element 9, with a vertically extending groove 12. This body is also provided ad jacent to groove 12 with a horizontally ex tending groove 13. In assembling the joint, the bolts are first inserted through the webs of the rail sections and plate 1, after which the inner locking plate 6 is placed in posi tion, this plate being provided with openings let to receive the bolts. After plate 6 has been moved into position against the web of the rail it is lowered so as to fit snugly into grooves 13 thus securing the bolts against longitudinal movement. After this has been done, plate 2 which is provided with openings 15 corresponding in size to the cross section of bolt 8, is placed in position with the edge portions of the plate adjacent to the openings 15 in groove 12. The nuts are then turned tightly onto the bolts so as to cause the plates to clamp the end portions ofthe rail sections and effectively brace the same, after which the locking washers. 11 are bent to secure the. nuts .as illustrated.

When plate 2 is in position shoulder 4 thereof presses upon the upper edge of plate.

6 so as to positively secure this plate against upward movement, the two plates. 2 and 6 cooperating with the shoulder 1- to effectively brace the rail head 5. After plate 2 has been moved into locking engagement with bolts 8, it is secured toties 16 by spikes 17 driven through openings provided in.

flange 18. of the plate for this purpose, and plate 1 is secured to the ties in a similar manner. When the joint is thus assembled the rail sections are rigidly connected and are eifectively reinforced and braced so as to eliminate all looseness or pounding at the joint.

What I claim is 1. In a rail joint, in combination with two adjacent rail sections, a plate positioned at one side of the rail sections, an inner looking plate at the opposite side of the rail sections, an outer locking plate positioned adjacent to the inner locking plate, and means for securing all of said plates together and to the rail sections, said securing means and the locking plates being provided with cooperating means for preventing movement of the securing means into inoperative position.

2. In a rail joint, two adjacent rail sections, a plate positioned at one side of the rail sections, securing members carried by said plate and extending through the webs of the rail sections, each of said securing members being provided adj acentto the opposite side of the rail sections with a horizontal groove and a vertical groove, and two contacting locking plates positioned at the said opposite side of the rail sections, one of said plates being in contact withthe rail sections, said locking plates being provided with openings to accommodate the securing members and one of the locking plates fitting into the horizontal grooves of the securing members and the other plate fitting into the vertical grooves of said members. p

3. In a rail joint, two adjacent rail sections, a plate positioned at one side of the webs of said sections, securing members car-- ried by said plate and projecting through said Webs, each of said members being provided in one side with a vertical groove and in its upper face with a horizontal groove, aninner locking plate at the opposite side of the rail sections having openings accommodating the securing members, said inner plate fitting intosaid horizontal grooves,

and an outer'locking plate in contact with said inner plate and having openings accommodating said securing members, the outer plate fitting into said vertical grooves.

4. In a rail joint, two adjacent rail sections, a plate fitting againstone side ofsaid sections, an inner locking plate fitting, against the opposite side of the rail sections,

an outer locking plate fitting against said inner plate, securing members carried by the first mentioned plate and extending through the websof the rails and both looking plates, each of said members being provided in its upper face with a transverse groove and in one lateral face withIa vertical groove, said inner looking plate fitting into the transverse grooves in the upper faces of the securmg members and the outer locking plate fitting into the vertical grooves of said members, and means carried by the outer locking plate for preventing rising of said inner plate. 7

5. In a rail joint, two adjacent rail sections, a plate fitting against one side of said sections, an inner locking plate fitting against the other side of the rail sections, an outer locking plate fitting against said inner plate, securing members carried by the first mentioned plate and extending through the webs of the rail sections and through both of the locking plates, each of said members being provided in'its upper face with a transverse groove and in one lateral face witha vertical groove, the inner and outer locking plates fitting snugly into saidtransverse and vertical grooves respectively, and an element carried by, the outer locking plate and fitting tightly between the rail head and the upper edge of the inner locking plate so as to prevent upward V movement of sald inner plate and brace the rail head. 7 r

6. In a rail joint, two adjacent'rail sections, a plate fitting against one side ofsaid sections, an inner locking plate fitting against the other side of the rail sections, an outer locking plate fitting against the 'inner plate,'bolts secured through all of A-MILE D. BISHOFF. i
